CORE HOLDER 0R SUPPORT.

Application filed April 13, 1920. Serial Ito. 373,572.

To all whom it may concern:

Be it known that HARRY ARTHUR Foo'r- HORAP, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, has invented certain new and useful Improvements in Core Holders or Supports, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a novel core holder or support for paper, carbon and other rolls.

The invention has for its object, to provide a holder by means of which the hollow core of a paper or other roll may be quickly and properly mounted on the spindle of a writing-adding or other machine in connection with which the paper or carbon is used.

In the accompanying drawings Fig. 1 is a sectional elevation showing a roll spindle and, in section thereon, a core holder carrying the paste board or other hollow core of the paper or carbon roll.

Fig. 2 is a detailed view of one of the bowed members of the holder.

Fig. 3 is a perspective view of the spindle with the core holder mounted thereon, and

Fig. 4 is a transverse section substantially on the line 44 of Fig. 1.

-1 indicates a spindle having the usual head 2 and adapted to be rotatably mounted in a stand or other support constituting part of the equipment of a writing, adding or other machine with which paper, carbon or similar rolls are used. These rolls are usually wound by the manufacturer upon a hollow tube or core 3, of paste board or other cheap material and it is necessary to provide some means whereby these cores which are of considerably greater diameter than that of the spindles, may be concentrically mounted on said spindles to rotate therewith.

For this purpose, I have devised a core holder l, comprising end discs 5, approximating the internal diameter of the core and having axial openings 6 of approximately the diameter of the spindle 1, which usually constitutes an element of the machine equipment. Between the discs 5 extend two or more, preferably three, longitudinal members 8 in the form of rods, equidistantly spaced from each other and having their ends extended securely into the discs 5. The longitudinal members or rods 8 are resilient and are slightly bowed outwardly to form a resilient or com ressible holder or support for the core 3. he outward bowing of the rods 8 makes the normal diameter of the holder somewhat greater than the internal diameter of the core but since these rods may yield inwardly it follows that the core may he slipped endwise upon the holder and forced into position, as shown in Fig. 1, against the resistance of the rods or members 8. The resiliency of the holder thus effects the frictional retention of the core and compels the latter to move with the holder as the latter is rotated.

The holder 4; may rotate on the spindle 1 but usually the spindle itself rotates and I, therefore, provide a coupling or separable connection between the spindle and the core holder. This connection is formed by recessing one of the discs 5 at opposite sides of the axial opening thereof, as indicated at 9 and by passing the pin 10 through the spindle with its ends projecting beyond the surfaces thereof to engage the recesses 9. Thus, while the holder is compelled to rotate with the spindle it may be readily slipped endwise therefrom when it is desired to remove the holder from the core of a used roll. The holder may be then slipped into the core of a new roll and replaced upon the spindle in an obvious manner.

WVhile the illustrated construction constitutes one embodiment of the invention, it is obvious that many variations may be effected within the scope of the protection prayed.

What I claim is 1. A core holder comprising a pair of axially apertured discs, a series of spaced resilient rods terminally secured to the discs within the peripheries thereof and bowed outwardly beyond the plane of said peripheries, whereby a core of an internal diameter corresponding approximately to the diameter of the discs will be engaged by both the disks and rods when forced upon the holder.

2. The combination with a spindle having a head, of a core holder comprising a pair of axially apertured discs, one of which is In testimony whereof I- hereunto afiix my seated against the head of the spindle and signature in the presence of two witnesses. connected to the spindle to rotate therewith,
